Answer:

f(x)^-1=x+12

Step-by-step explanation:

f(x)=x-12

y=x-12

x=y-12

PLEASE HELP 33 POINTS AND I WILL MARK BRAINLIEST!!!!!!!! THANKS!!!!!!!!!!!
zysi [14]

(a) Volume of any Pyramid =   \frac{1}{3} * (Base-Area)*height = \frac{1}{3} *220.22*9 = 660.66 cubic units

(b) Sarah doesn't have to go through all the hard work as the smaller pyramid has a ratio of 2:3 to the bigger pyramid, so we get the equation, to help us solve it.

660.66 = \frac{2}{3} *(Area-of-larger-pyramid)

Hope that helps!

Find the value of x that makes def ~ xyz<br>x=​
Neporo4naja [7]

Answer:

x = 3.5

Step-by-step explanation:

\triangle DEF \sim \triangle XYZ\\\\\therefore \frac{DE}{XY} =\frac{DF}{XZ} \\\\\therefore \frac{5}{7.5} =\frac{7}{3x} \\\\\therefore 3x = \frac{7.5\times 7}{5} \\\\\therefore x = \frac{7.5\times 7}{3\times 5} \\\\\therefore x = \frac{52.5\times 7}{15} \\\\\therefore x = 3.5

Precal : Note: Triangle may not be drawn to scale. Suppose a = 3 and A = 15 degrees
drek231 [11]

Given:

In a right triangle at B,

\begin{gathered} a=3 \\ A=15^{\circ} \end{gathered}

To find:

The length of the sides b and c and angle B.

Explanation:

Using the trigonometric ratio,

\begin{gathered} sinA=\frac{a}{c} \\ \sin15^{\circ}=\frac{3}{c} \\ c=\frac{3}{\sin15^{\circ}} \\ c=11.59 \\ c\approx11.6 \end{gathered}

Using the trigonometric ratio,

\begin{gathered} \tan A=\frac{a}{b} \\ \tan15^{\circ}=\frac{3}{b} \\ b=\frac{3}{\tan15^{\circ}} \\ b=11.19 \\ b\approx11.2 \end{gathered}

Using the angle sum property,

The angle B becomes,

\begin{gathered} 90+15+B=180 \\ B=180-90-15 \\ B=75^{\circ} \end{gathered}

Final answer:

The values are,

\begin{gathered} b=11.2 \\ c=11.6 \\ B=75^{\circ} \end{gathered}
